Often, fly ash is looked upon as a measure to bring down the cost of concrete, But fly ash can also enhance properties and reduce cement consumption. A proper insight into the possible mechanisms of concrete deterioration has led to altering of the properties of OPC concrete

Dr Vimal Kumar is Secretary General, C-FARM, an entity devoted to scientific and techno-managerial guidance and consultancy for adaptation of fly ash utilisation. He speaks on the latest developments on this front.

To keep open a realistic chance of meeting the target of restricting the global average rise in temperature below 20C, as envisaged in the Paris COP21, intensive and innovative actions are required by the cement industry, which happens to be a significant contributor to the total anthropogenic emission of CO2.
